【答案】Dear friends,

Our school produces a lot of rubbish every day, such as leftover food, waste paper and plastic bottles, which brings a wide range of environmental problems as well as the waste of resources. Therefore, it's time we took immediate measures to change the situation.

First of all, it is necessary for us to raise awareness of environmental protection and develop the good habit of garbage sorting. What's more, we should voluntarily differentiate recyclable rubbish from non-recyclables in our daily life.

In a word, if everyone does his/her bit responsibly in garbage sorting, our school will become better and better. It will also contribute to sustainable development. So, take action right now!
